A method includes: receiving a circuit design including circuit stages; deriving initial logic conditions for nets in a fanout cone from an input port in accordance with a primordial event; initializing a priority queue of logic transition events with the primordial event; determining a trigger event from the priority queue, the trigger event having a timestamp equal to or earlier than all others in the priority queue and representing a logic transition at an input pin of a current circuit stage; simulating an arc of the circuit design from the input pin of the current circuit stage to an input pin of a fanout circuit stage to generate a propagated event; computing a propagated event timestamp based on: the trigger event timestamp; and a delay associated with the arc; enqueuing the propagated event on the priority queue; and generating a static analysis report based on the propagated event timestamp.
